＊ Nest Owners, please note that this app will work for you if you are on a Nest account created before September 1, 2019, that has not been migrated to a Google account. Right now, it does not support login with a Google Nest account created after the September 1st. Support for Google accounts is coming in early 2020, once Google launches their new Device Access program. Note also that if you are on a Nest account, migration to Google account is not mandatory.
＊ The app has Siri Voice shortcuts for seamless Siri control of your Nest, from the iPhone, Watch and HomePod. It fully supports Apple Watch LTE, and can work when the iPhone is not around - as long as the watch itself has internet access (either LTE or WiFi).
＊ The app lets you monitor and control HomeKit thermostats like Ecobee, and functions largely the same with them as it does with Nest, except for the Siri Shortcuts functionality which is not needed with HomeKit. It lets you see your thermostat info on the Watch complications, and control it using the iOS widget.
• Using Siri voice shortcuts you can control many aspects of your Nest, such as instant activation of heating or cooling, direct setting of your favorite temperatures, increasing/decreasing the temperature, and setting the Home/Away state. Thanks to Thermo Watch, It's all finally just one casual "Hey Siri" away, all with informative visual and verbal feedback.
• From the watch face, tap on the Thermo Watch complication to open the app. Spin the Digital Crown, or Swipe up/down to adjust the temperature. You can start adjusting the moment the app opens.
• On your iOS device you can press firmly onto the app icon to open a quick popout menu, you can swipe to the notification center to adjust the temperature on the Widget, or you can just open the app. Again, you can start adjusting the moment the controls appear.
• From your Apple TV, open the app, and swipe up/down on the remote to change the temperate.
The app will let you know with a chime and a tap, that the thermostat has received and applied your command.
Monitor your Thermostats and Home/Away status right from the watch face, using complications that update in the background, without having to launch the app.
You can use Siri on your iPhone, Watch, iPad, or HomePod to control any of your thermostats. Record phrases that make most sense to you, such as "Start Heating" or "Make it Cooler". If you have multiple thermostats you can control them individually, by saying for example "Start Heating Upstairs" or "Start Cooling the Living Room".

Set Geofence around your home to reliably set the Home and Away state when you come and go.
The app supports multiple thermostats in multiple homes - just swipe left and right on your Watch screen to access them, or see them all at the same time in the iOS Widget and the app. Fahrenheit and Celsius are both supported.
Beyond that, you can press the Watch screen firmly for additional functions, like switching to a heating or cooling mode, setting the away status, or turning the fan on and off.
While the app's minimalist looks betray the simplicity of its operation, what they don't show is the amount of planning, design, development and refinement that went into it, ensuring it becomes something that is enjoyable to use and experience.
The goal was to make a product hat would not look out of place next to one of the apps bundled with the Apple Watch.
Please note also that this app can't work with Thermostat E with Heatlink, sold in Europe.
Thermo Watch does not collect any of your data. Your login information, thermostat settings, and any activity - all of it flows exclusively between your devices and Nest. Author of Thermo Watch does not receive any of it, at any point.
＊ This app allows users to log in and control their Nest Thermostats - as long as they are on a Nest account created before September 1, 2019, that has not been migrated to a Google account. Right now, it does not support login with a Google Nest account created after the September 1st. Support for Google accounts is coming in early 2020, once Google launches their new Device Access program. Anyone with a Google account who has already purchased the app - feel free to contact email@example.com for a refund.
＊ Tip Jar added to the app menu. If Thermo Watch has changed your home experience for the better, please consider giving a small tip.
＊ Low home temperature warning alert is added to the Watch App settings. You can set a temperature that, if reached or dipped below, will show an alert on your Watch. This function is a Watch-exclusive, and it requires that you have the Thermo Watch complication enabled on your watch face. It can come in handy in case your furnace is faulty, and doesn't heat, even though the thermostat thinks it's heating.
＊ Apple TV app is now functional for new users too. (Nest users only)
＊ All homes are now correctly scanned for HomeKit thermostats, not just the primary home. Many thanks to Greg for helping me troubleshoot this!
＊ Added Contact Support buttons on the login page, and in the app menu.
＊ Watch app setting added to disable the confirmation sound chime.
＊ Fix for the "Object is not associated with a home" error in the widget with HomeKit thermostats.
＊ Fix for the watch face complication not updating throughout the day.
＊ Added the ability to log in with the Nest API key. Please save your API Key using the menu option in the app. If the option is available to you, it will be in the menu that opens when you tap the menu button in the top/left corner. It could prove useful in future-proofing the app for users who wish to stay on the Nest account.
Other recent updates:
＊ New iOS13-only Siri shortcut - "Set Mode" added. This shortcut will have Siri ask a followup question for what HVAC mode to set. In the Shortcuts app, this shortcut can be preconfigured to set a specified mode. It can also be configured to accept the output of the previous action as the mode input. Some of the valid mode phrases are "Heat", "Cool", "Heat and Cool", "Heat mode", "Heating", "Eco mode", etc.
＊ New iOS13-only Siri shortcut - "Set Target Temperature" added. This shortcut will have Siri ask a followup question for how many degrees to set. In the Shortcuts app, this shortcut can be configured to set a specified temperature, so that way you can have as many "Set Favorite" temperatures as you like. It can also be configured to accept the output of the previous action as the temperature input, replacing the old and inelegant "Clipboard to Target Temperature" shortcut.
